We have published our new patch after hearing your feedback. Not all changes that we are planing to make are implemented in this patch but this is a good start.
-Nerfed the Scarabei alien (movement speed and HP nerf)
-Nerfed Walker alien speed
-Fixed the hitbox bug ( players reported that they sometimes died even though enemies did not touch them. This was due to the game registering the weapons as player hitboxes.)
- Added more shield spawners in the One Life Mode ( One life mode was too difficult, that is why we created special platforms that spawn only shield's periodicaly)
-We reduced the time needed to complete each level of one life mode
-There is more explanation at the start of One life mode ( like that the score is multiplied in one life mode and that laser wall's will kill the player on contact)
-Set the respawn location at the start of lvl 1 instead of the tutorial coridor
-And most importantly added a mute music option to the game
We hope that this will make the game feel more fun and we will definitely implement more suggestions in patch 1.2. In the meantime please let us know what else you would like to see improved/changed.
